وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، حَدَّثَنِي عَبْدَةُ، بْنُ أَبِي لُبَابَةَ عَنْ شَقِيقِ بْنِ سَلَمَةَ، قَالَ سَمِعْتُ ابْنَ مَسْعُودٍ، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ بِئْسَمَا لِلرَّجُلِ أَنْ يَقُولَ نَسِيتُ سُورَةَ كَيْتَ وَكَيْتَ أَوْ نَسِيتُ آيَةَ كَيْتَ وَكَيْتَ بَلْ هُوَ نُسِّيَ ‏"‏ ‏.‏
